There may be nothing cuter than a polar bear cub. Except, of course, multiple polar bear cubs. And a full-grown adult polar bear thrown in for good measure.

That's the un-bear-ably (sorry) cute scene photographer Thomas Kokta captured in the wilderness of Manitoba, Canada, earlier this winter, as he documented the young polar bear cubs emerging from their dens. Per a release from the Caters photography agency, fewer than 500 people are estimated to have witnessed polar bear cubs emerging from their dens in the wild.

And they weren't just any polar bear cubs, either. Armed only with his camera and what he says is a "rare operating permit," Kokta has had the good fortune of photographing polar bear triplets, an extremely rare occurrence.

Polar bears are considered a "vulnerable" species, with population declines expected to mirror deteriorating sea ice in the coming decades due to climate change. If warming trends continue, the International Union for the Conservation of Nature speculates polar bears could be completely displaced from their current habitat within 100 years.

A lucky photographer has managed to photograph these adorable images of young polar bear cubs.

Godfrey Mutuku Jones, a caretaker at Kenya's Wildlife Service orphanage, holds two, 3-month old female Cheetah cubs at the Nairobi Orphanage in Nairobi, Kenya, Monday, June 6, 2011. The two Cheetah cubs were abandoned by their mother, in Tsavo East, South of Nairobi, and were brought to the orphanage to be cared for by the Kenya Wildlife Service in Nairobi National Park.
